Sole for footwear



FIG. 1 is a right side view, showing my new design;

FIG. 2 is a bottom view thereof;

FIG. 3 is a left side view thereof;

FIG. 4 is a front end view thereof; and,

FIG. 5 is a rear end view thereof.

The broken line showing of the sole in the figures is for illustrative purposes only and forms no part of the claimed design. Any surfaces that are not shown, including those that might appear in a top view, form no part of the claimed design. 

I claim the ornamental design for a sole for footwear, as shown and described.
